Checking unique recipe execution during parallel software builds

SF Markus Elfring
Hello,

I am testing my recent adjustments for a few build scripts. Now I wonder again
about an error message. But I guess that it should only be taken into account
when an other issue will be checked once more and resolved then hopefully.


elfring@Sonne:~/Projekte/Bau/OCamlbuild> LANG=C make -r -j4 byte

ocamlc.opt -pack -o 'o/ocamlbuild_pack.cmo' …

make: *** [GNUmakefile:1221: o/ocamlbuild_pack.cmi] Error 2


This compilation command is started twice in the shown software situation
while I would expect that the affected recipe should be executed only once
at the end of the attempted build process.
Do I observe further challenges for parallel software builds here?

Regards,
Markus
